IMPROVED PRESERVlNG-HOUSE.

Specification forming part of Letters Patent No. 35,943, dated July 22, 1862.

i do hereby declare that the following isa full,

clear, and exact description of the same, reference being bad to the accompanying drawings, making a part of this specification, in which t Figure 1 is a vertical section of my invention, taken in the line we", Fig. 2; Fig. 2, a horizontal section of the same, taken in the line 3 y, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

This invention consists in a novel arrangement of an ice chamber and waste-pipe within a building or structure, as hereinafter fully shown and described, whereby a continuous circulation of air is maintained within the building from top to bottom and the warm air as it enters the building immediately reduced in temperature and before it can come in contact with the articles to be preserved.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a building of any suitable dimensions and having double walls and a double bottom, as shown at a a.

B represents a chamber or compartment which is placed centrally within the building A and communicates at its upper end with a compartment, 0, which is formed by an inclined flooring, D, as shown clearly in Fig. 1. The chamber B extends nearly down'to the floor E of the lower compartment, F, of the building, a space, 12, being allowed underneath it for the circulation of air. The bottom 0 of the chamber B is inclined so as to form a gutter, d, at its center, one end of which communicates with a waste-pipe, G, which extends down to the floor E of the compartment F, and is coiled around upon it, as shown in Fig. 2, and then projects through the side of the building.

1 The compartment F is the one in which the articles to be preserved are placed, and the chamber B and all or aportion of the compartment C are filled with ice.

The operation is as follows: Cold air is radiated from the chamber B toward the sides of the building A, while the wastewater from the chamber B passes down through the pipe G' and around through it on the floor E, and

is discharged from its end at one side of the building. This cold waste water keeps the floor and lower part of the compartment F in a cool state, while'the radiation of cold air from B and from the flooring D keeps the other parts of said compartment at a low temperature. The warm air in entering the compartment F, which it does in various places through joints, 830., is immediately chilled by the cold air radiated from B, and ascends to the flooring D, and then passes toward the chamber B and downward by the sides of B to the floor E of F, as indicated by the arrows in Fig. 1. By this circulation of the air in F, which is due to the arrangement of the chamber B, compartment 0, and flooring D with l The building is provided with an ordinary roof, H, of shingles or boards, and the'walls may be of wood put together in any proper way, the whole being constructed as tightly as possible.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

The combination of the ice-chamber B and ice-compartment G with the waste-pipe G, arranged within the building A, as and for the purpose herein set forth.
